A rocket is moving at 1/4 the speed of light relative to Earth. At the center of this rocket a light suddenly flashes. To an observer at rest in the rocket a. the light will reach the front of the rocket before it reaches the back of the rocket. b. the light will reach the front of the rocket at the same instant that it reaches the back of the rocket. c. the light will reach the front of the rocket after it reaches the back of the rocket.

The correct answer is;

b. the light will reach the front of the rocket at the same instant that it reaches the back of the rocket.

Explanation:

The speed of light is an invariant. The speed of light is independent of the source or the observer, that is the speed of light does not depend on the speed of the source, or the speed of the observer, or the speed of the medium. The speed of light is constant, and as such the light will arrive at the back and front of the rocket at the same time.

b.a device that inputs heat into a cool object
